State-Changed-Why:
Not a bug. According to 26.3.3.2, operator== returns a
valarray<bool> *not* a bool. Indeed, this one compiles:
#include <valarray>
int main(int argc, char* argv[])
{
std::valarray<double> a(1.2, 10);
std::valarray<double> b(1.2, 10);
//bool equal = ( a == b);
std::valarray<bool> equal = ( a == b);
//return int(equal);
}
Cheers, Paolo
